Abstract :
The design considerations for permanent-magnet motors intended for brushless operation are discussed. Two rotor configurations are described: the imbricated rotor and the segmented rotor. The segmented rotor is designed specially for high-speed operation. A brushless DC (BLDC) drive system is also described, and the performance of a neodymium-iron-boron excited PM motor with an imbricated rotor in a BLDC drive is presented
